Value Collection MS01B1944B Worm Gear Clamp Sae 20

Product Description

The VALUE COLLECTION MS01B1944B is a worm gear clamp rated SAE size 20, designed to secure hose connections across a clamping range of 3/4 inch to 1-3/4 inches in diameter. The band is constructed from grade 201 stainless steel and carbon steel, measuring 1/2 inch in width. The worm drive mechanism allows incremental tightening with a standard screwdriver or nut driver, making it a reliable fastening solution for fluid and air transfer lines. Plumbers, HVAC technicians, and general trade mechanics regularly use this style of clamp on coolant hoses, radiator lines, duct connections, and low-pressure fluid fittings.

This clamp fits residential and light commercial applications where a compact, adjustable band clamp is needed on hose assemblies or tubing within the 3/4 inch to 1-3/4 inch outside diameter range. It is well suited for use on rubber, silicone, and vinyl hose connections found in plumbing, HVAC condensate lines, automotive coolant systems, and pool equipment plumbing. The 1/2 inch band width provides adequate sealing surface contact for standard hose barb and slip-fit fittings without over-stressing softer hose materials.

Key Features

• SAE size 20 worm gear clamp with a clamping range of 3/4 inch to 1-3/4 inches
• Band width of 1/2 inch for consistent sealing surface coverage
• Grade 201 stainless steel and carbon steel band construction for corrosion resistance in wet environments
• Worm drive design allows precise adjustment with a flat-blade screwdriver or 5/16 inch hex nut driver
• Lightweight at 0.03 pounds, suitable for space-constrained installations

Compatibility

Designed as a standard SAE 20 worm gear clamp for use on hoses and tubing with an outside diameter between 3/4 inch and 1-3/4 inches across plumbing, HVAC, pool, and general mechanical applications.

Installation Notes

Installation is typically performed by plumbers, HVAC technicians, or pool service professionals. Depressurize and drain the line before removing any existing clamp or hose fitting. Position the clamp over the hose before seating the hose onto the fitting, then slide the clamp into place at least 1/4 inch from the end of the hose. Tighten the worm screw evenly to seat the band without overtightening, which can cut into soft hose materials.
